Here's a dumb question:

I've been trying to render a few Poser sets and I keep getting a blank gray ground in Lux. (The floor geometry of the sets aren't showing up, but they're fine in Poser)

Is this Poser's default ground plane showing up? (I hid it in Poser)

I haven't touched Poser in years, so I have no clue what I'm doing wrong!
